We have a 2012 24V on a 2011 chassis. We have a lot of wandering and steering seems loose. The unit has 14,000 miles on it. Is this a known problem with this chassis? Anyone had this issue?
While I think the caster discussion is on point and beneficial, I do think you need to distinguish between loose steering and wandering due to incorrect caster. It never hurts to have someone watch your front suspension while you turn the centered steering wheel back and forth a half inch to an inch, and be sure that movement translates to the front wheels. On my E450 there is no play in the steering, all movement moves the front wheels at least a little.
